PENTAX K-1

PENTAX K-1

Developed as the flagship model of the acclaimed PENTAX K series of digital SLR cameras, this new model features a large CMOS image sensor, equal in size to the full image area of 35mm film, to deliver super-high-resolution images required for the artistic work of photo enthusiasts and professionals.

Equipped with a large, high-performance CMOS image sensor (35.9mm by 24.0mm) and supported by approximately 36.4 effective megapixels and PENTAX-original imaging technologies, the PENTAX K-1 assures super-high-resolution images rich in gradation and superb in high-sensitivity rendition. Thanks to its large image sensor, the camera provides the same depth of field as a 35mm film-format camera, and allows the user to create a fine bokeh (defocus) effect more effectively than before. By further advancing its unique technologies, accumulated over decades of camera development, PENTAX has also equipped the K-1 with a host of the latest technologies. A new-generation shake reduction mechanism effectively reduces camera shake along five axes with a compensation range of five shutter steps. This mechanism also shifts the image sensor unit by a single pixel to assure super-high-resolution digital imaging. An extra-accurate exposure-control mechanism is supported by state-of-the-art artificial intelligence technology. Within its compact body, the K-1 also provides an array of PENTAX-original features and functions, such as a flexible tilt-type LCD monitor that can be tilted to the desired angle horizontally and vertically without deviating from the lens’s optical axis; an Operation Assist Light function to facilitate camera operation in the dark; and an optical viewfinder with a nearly 100-percent field of view. In addition to an assortment of interchangeable lenses — from old film-era lenses to the latest D FA-series models — the K-1 also accepts more compact DA-series lenses with a smaller image circle, with the help of its Crop function.

The K-1 incorporates a newly developed 35mm full-frame CMOS image sensor, one that assures the highest image quality to be found in the K-mount SLR series. Thanks to its large imaging area and wide pixel pitch, this high-pixel sensor delivers lively, trueto-life images with rich gradation and minimal noise. Its shallow depth of fi eld allows you to control the sense of depth and bokeh (defocused) effect at will.

PRIME IV

A new imaging engine optimized for a 35mm full-frame image circle

The K-1 features a newly designed PRIME IV imaging engine. Compared with the previous PRIME III version, it is fi ne-tuned to process higher-resolution images, while boosting the operating frequency by nearly 50 percent. Its noise-processing algorithm has also been upgraded to capture beautiful, fi ne-gradation images at higher sensitivities. A combination of an advanced scene analysis system and new imageprocessing functions helps improve the accuracy and reliability of image reproduction.

ISO 204800

A combination of super-high sensitivity and exceptionalimage resolution

By taking full advantage of the image sensor excelled in noiseresistance performance and the PRIME IV imaging engine, the K-1 provides a top sensitivity of ISO 204800 (at standard output sensitivity). This not only delivers high-resolution images free of tone jumps and graininess at high-sensitivity settings, but also improves image quality in the low-sensitivity range. Since the K-1 allows you to raise the sensitivity level to capture images equal in image quality to those taken at lower sensitivities, it expands the boundaries of photographic expression.

Dependable dustproof, weather-resistantconstruction

A completely environment-resistant imaging system, with a weather-resistant lens

A combination of the K-1’s 87 sealing parts and the optional D-BG6 Battery Grip’s watertight body prevents the intrusion of water and dust into their interior. When an AW or WR-series lens is mounted,* the K-1 and its lens forms a remarkable digital imaging system totally resistant to demanding environmental factors.

Anticipating many users’ needs for photo shooting in extremely cold locations, the Anticipating use in cold locations, PENTAX has subjected the K-1 to exacting environmental tests at temperatures as low as –10°C, and gathered a vast array of data on operational precision, response and stability of mechanisms and circuits, as well as fl uctuations in battery voltage.

* As the result, the K-1 assures solid, troublefree operation even at freezing temperatures.

* Battery performance declines as the temperature goes down. When shooting in cold environments, the user is advised to carry spare batteries and keep them warm by storing them in an inside pocket.

High-rigidity, extra-durable body

The K-1’s exterior casing is made of highly rigid, lightweight magnesium alloy, which provides excellent shock-resistance and electromagnetic shielding performance. By coupling it with a high-rigidity metallic chassis housing the core components, the K-1 forms a compound structure to assure outstandin durability and exceptional reliability.

Extra-durable shutter unit

Withstanding 300,000 shutter releases for professional use

After a series of exacting performance tests, the K-1’s shutter unit has proven its exceptional durability by withstanding a total of 300,000 shutter releases. It assures outstanding operational precision and exceptional durability required for exacting professional work.

Reinforced with the SR (Shake Reduction) mechanism, the K-1’s Pixel Shift Resolution System* captures four images of the same scene by shifting the image sensor by a single pixel for each image, then synthesizes them into a single, super-high-resolution composite image. Compared to the conventional Bayer system, this innovative system obtains all RGB color data in each pixel to deliver beautiful images with far more truthful colors and much fi ner details, without any hint of false color. This system also reduces high-sensitivity noise to a minimum. The diff erence in image quality is evident at a glance, even without magnifying the captured image on a computer screen or producing a large-size print. Images captured by the Pixel Shift Resolution System can be saved as RAW-format files. You can developed these files within the camera body while adjusting various parameters or turning the Pixel Shift Resolution eff ect on and off to create a new image.

* When using this system, the user is advised to stabilize the camera firmly on a tripod during shooting by setting the drive mode to self-timer or remote control, or using the mirror lock-up function.

* When the subject is on the move or camera shake occurs, the desired eff ect may not be obtained.

The PENTAX-original sensor-shift-type shake reduction mechanism has been upgraded to provide optimum compensation for all lenses used in handheld shooting. The new-generation SR II (Shake Reduction II) features a fi ve-axis mechanism to compensate for camera shake caused by horizontal and vertical shift** (often generated in macro photography) and camera shake caused by roll, which is difficult to handle by lens-installed shake reduction mechanisms, in addition to more common camera shake caused by pitch and yaw. The SR II unit is controlled with great precision as soon as the camera’s power is turned on, and provides a wide compensation range — as much as five shutter steps*** — to expand the limits of handheld shooting.

*For a 35mm full-frame digital SLR camera, as of February 2016(based on RICOH IMAGING research).

**During Live View shooting, this mechanism does not compensate forcamera shake caused by horizontally and vertical shift.

*** Measured in conformity to CIPA standards, using an HD PENTAX-D FA 28-105mm F3.5-5.6ED DC WR lens at a focal length of 105mm.
